Lakes Must-Do rides

Looking at doing a week's biking in the Lakes in the summer.
I've done quite a few rides there over the years but still a few I want to do.
Has anyone done the likes of Nan Bield, Black Sail, Grasmoor? I know a few have done Ullock Pike (Skiddaw) but that's a bit of a naughty one best saved for when the redsocks aren't out in force

I used to count a big loop of Coniston Water in there too, but since some OTT resurfacing work on Walna Scar road, its not what it was. To summarise: clockwise from Coniston village around to Grizedale forest, south down Parkamoor, west across Blawith Moor on to Stephenson Ground, then up to Walna Scar Road and descend to Coniston.
